2 I will cover Incidence, consequences & costs of Falls & Osteoporosis Current Research Policy Physical Activity Recommendations for Falls prevention & Osteoporosis Plus where to find out more! This presentation will be available on the LLT website (Publications)

3 AGEING AFFECTS ALL OF US 1-2% in functional ability p.a. Strength Power Bone density Flexibility Endurance Balance and co-ordination ordination Mobility and transfer skills Sedentary behaviour accelerates the loss of performance...

4 active, strength-trained 70 yr old females sedentary The same difference in muscle size is seen between a 30 and an 80 yr old (Adapted from Sipilä & Suominen Muscle Nerve 1993;16:294)

5 Falls & Fractures in the UK 11 million people aged > 65 yrs 28,000 women aged > 90 yrs Fractures costs 1.6 billion pa 1 Hip Fracture every 10 mins Cost k 1 Wrist Fracture every 9 mins Cost Spine Fracture every 3 mins 500 admitted to Hospital every day 33 never go home Annual European Home and Leisure Accident Surveillance Survey (EHLASS) Report UK 2000

6 Not all falls lead to fractures..or injuries

7 Consequences of Falls Post fall syndrome & fear Injuries include: Cuts and lacerations, Deep bruises, Soft Tissue Injuries, Dislocations, Sprains Increase in joint pain 20% of falls result in fractures requiring hospital treatment.

8 Fear and avoiding activity Present in >50% of fallers & up to 40% non- fallers Predicts decreases in physical and social activity deterioration in physical functioning higher risk of falling Improves with exercise, as does balance confidence and self efficacy

9 We need to prevent falls In > 75s, falls are the leading cause of death resulting from injury 75-80% of falls are not reported 10% of all call-outs for UK Ambulance Service are for people aged 65+ who have fallen but nearly half are not taken to Hospital. WHO Health Evidence Network Preventing Falls Briefing 2004

10 Long-term Institutionalisation Fall related accidents are predisposing factors in 40% of events leading to long- term institutional care in older people [Kennedy et al Dan Med Bull 1987]

11 Residential Settings 75% fall annually (1.5 falls per bed per year) 35% of falls result in serious injury up to 8% of falls result in fractures Hip fracture incidence higher SCARE Briefing -

12 Long lies with or without injury Long lies (> 1-2 hours) lead to an increased risk of: dehydration hypothermia pneumonia pressure sores kidney failure depression post fall syndrome death (Tinetti 1993, 1994)

13 Osteoporosis Affects 1 in 3 women and 1 in 12 men over 50. Osteoporotic fracture every 3 minutes. High level of associated morbidity and mortality. Osteoporosis increasing by 10% per year.

14 In people who have a hip fracture: 2 out of 10 regain previous mobility 5 out of 10 die or become dependent within a year

15 Burden on health care resources 4,500,000 4,000,000 3,500,000 3,000,000 Mean LOS all ages 7.9 days Mean LOS # femur 25.7 days Mean LOS falls 9.67 days 2,500,000 2,000,000 1,500,000 1,000, ,000 - All fractures >60 yr + falls >75 yr.* Fracture femur >60 yr.* Diabetes all ages Cardiac ischaemia all ages Heart failure all ages COPD + asthma all ages Stroke >60 yr*

17 IMPACT - Costs to the NHS Hospital spending > 10 billion. Local authority, residential care > 3 billion Non-residential care > 2 billion. Half of L.A. social services spent on services for older people Formal and informal care Emergency call-outs

18 Can exercise prevent fractures? Lifetime risk of hip fracture Men 3 in 100 Women 15 in 100 Fractures more common in sedentary people It is possible to increase BMD in older people (Welsh 1996; Kohrt 1995; Verschueren 2004) It is possible to increase BMD in fallers fallers (Skelton 2005; Liu Ambrose 2004)

23 We are all trippers When do we become fallers?

24 Sensory Input Stability Three main sources of input Visual information Vestibular information Proprioceptive information

25 Lessons that last a lifetime

26 Falls Risk Not modifiable with tailored exercise age social class gender multiple medications chronic medical conditions vision problems poor heating and poor housing malnutrition poor footwear exercise may not have a major effect Falls Risk modifiable with tailored exercise low strength low power poor mobility poor balance arthritis depression fear of falling postural hypotension urinary urgency exercise is likely to have a major positive effect

27 Exercise to Prevent Falls Exercise could help fallers or prevent falls and fractures Reducing Falls (or injurious falls) Reducing known Risk Factors for Falls Reducing Fractures (or changing the site of fracture) Increasing Quality of Life & Social Activities Reducing Fear Reducing Long Lies Reducing Institutionalisation

28 Exercise to Prevent Falls Unifactorial Approach Province, 1995 Wolf, 1996 Campbell, 1997 Robertson, 2001 Day, 2002 Barnett, 2003 Lord, 2003 Skelton, 2004, 2005 Group and individual balance and strength training >65 s Group Tai Chi >65 s (NOT >70 s at risk, Wolf 2003) Home-based exercise >80 s Home-based exercise >65 s and >80 s Group exercise >70 s at risk Group exercise >65 s at risk Group exercise >60 s retirement village Group Exercise >65 s frequent fallers

29 FaME Group Exercise Managing frequent fallers Women aged 65+ with a history of 3 or more falls in previous year 9 months community based intervention Group exercise individually tailored, trained exercise instructors (PSIs), one class a week (1hr) & 2 x 20 minute home sessions Falls risk decreased by half RR 0.46 Significant improvements in strength, power, functional ability, balance and reaction times Skelton et al. Age and Ageing, 2005: 34:

32 FaME Group based Exercise Falls risk decreased by half RR 0.46 Significantly less people in exercise group had died, entered a nursing home or were in hospital after 3 years 10% in exercise group had died, were in Hospital or in a nursing home compared to 33% of those not exercising Skelton et al.

45 Policy on Falls NSFOP NICE 21: Falls guidelines All Party Parliamentary Osteoporosis Group (APPOG): Falling Short World Health Organisation Health Evidence Network Document: Falls risks and prevention National Service Framework for Older People: Department of Health Local Initiative Mapping RCP Audit of Falls & Osteoporosis Services

46 NSF OP Standard 6, 2001 The NHS, working in partnership with councils, takes action to prevent falls and reduce resultant fractures or other injuries in their populations of older people. Older people who have fallen receive effective treatment and rehabilitation and, with their carers, receive advice on prevention through a specialised falls service. (1) Prevention. (2) Diagnosis & management. (3) Rehabilitation and longer term care. Key Milestone April 2005

47 The evidence for factors which increase the risk of falling The most effective methods of assessment and identification of older people at risk of falling The most clinically and cost effective interventions and preventative strategies for the prevention of falls Older peoples views and experiences of falls prevention strategies and programmes.

50 PA Recommendations for Falls Prevention Type Mix Balance and/or mobility ***** Resistance exercise *** Lower limb Most effective in weakest Aerobic / Endurance ** Flexibility ** Functional Task Training ** Endurance or resistance training alone does not work

51 Tai Chi to prevent future falls Tai Chi should be considered as an effective preventative strategy at reducing the risk of having a fall in the first place If a person is already a faller or very frail, Tai Chi may not be the most effective form of exercise If a person is already a faller or very frail Tai Chi moves will have to be adapted and it may be more effective to pursue other balance training techniques

52 Exercise to prevent falls To date, effective exercise programs comprise a combination of challenging and progressive balance exercises performed in weight-bearing positions that minimise the use of the upper limbs for support. resistance and endurance training combined with the balance exercises. To date, effective exercise programs have been individualised in intensity progressed over time targeted to an appropriate population conducted by trained personnel of a sufficient duration (greater than 15 weeks, preferably 6 months or more) Whitney et al. 2006
